Bosch ignition lead for sale
I bought these http://www.ebay.com.au/itm/BOSCH-MOTORSPORT-SPARK-PLUG-LEADS-MITSUBISHI-LANCER-PAJERO-4G93-OUTLANDER-4G64-/200501492350 a couple of month ago.
I got my car serviced recently and they replaced the leads and plugs. So basically, I am not going to use them....
I have seen them, cheaper that what I got them for in "Supercheap"...bugger...!.
I got told that they will fit the 1.6/1.8/2.0 engine too. (in Bosh listing) They are the Bosch B4314HP (set of 2 leads, as written on the box) new never fitted.
Make an offer. Free postage, Australia only. (I might cut the box to make it smaller/cheaper to post).
Happy io.
Ht leads
Hi Claude, if not too late or a hassle for you - could you please put a multimeter across the new HT leads and report back on the resistance? I haven't had a look in the docs to see if this is published but would be good to know what a known healthy set measures.
... Assuming this is a valid way to test for faulty leads?
lead resistance
I am a bit busy but I always find a bit of time....the small one is 188 ohms and the longer one is 345 ohms, I thought that it would be more....anyway that what I have measured. Yes it is a correct way to check them. There is a certain amount of resistance per foot to have but I don't remember the actual rule....

Doh
These leads are for a 4G64 right? Just realised my 4G93 leas will have different specs anyway, but tha info may be useful for someone else one day....
I just tested mine and got 1.016 ohms for the short lead, 1.268 for the long. Now how to find out if this is in the normal range.... By the way, the problem I'm poking at is a bit of hesitancy and occasional misfire under load at under 3k rpm. Resetting the plug gaps has helped but its still not 100%.
leads
This is from far memory....I think that 7k ohms per foot is ok, over and they need replacing, so I would say that your set is good.(again this is far away memories) I am not sure about the specification that you mentioned regarding the leads because the Bosch listing (not what is on the box, not complete listing) have the same replacement for the 1.6/1.8 and the 2 litre.
I have checked the leads on the 99 io and I found 2.9k ohms for the long one and 1.5k ohms for the short one. These are old set.
If your spark plug needed adjusting, they may be worn out....
I fitted a new set of spark plug today, I got a friend who gave me a set of NGK iradium :) I have to wait a bit more to comment on these, but so far the engine seems a bit more responsive....nothing much....

Plugs & leads
I was intending to fit new plugs today but found the ones that Repco gave me aren't the right ones - they gave me NGK 6E which have double poles on them. What I have fitted now, and I think are correct for the 4G93 engine, are 5E which are conventional single pole design. I'll take them back and swap for 5Es tomorrow.
The Bosch list you have - does it specifically say the 1.8 SOHC 4G93. There is a 1.8 GDI engine and perhaps it's only referring to that? If they are all meant to take the same leads, then why are my resistance measurements so very different to yours.... Hmmm
leads
My understanding...please correct me if I am wrong.....
The resistance of the leads do change depending on how they are made, quality, but with age, and use as well. The chances to have the same reading between 2 identical car is slim.
The resistance does increase with use and age and after a while this resistance increase so much that the current doesn't flow through to supply correctly the spark plug.
Again, from old memory lane....I think that the lead start to not work properly when they reach the 7k ohms per foot. I had a quick look on google to bring some memory back but I have to read a bit more....what I have read haven't help much ...so far..., some say even 10k per foot ( that seems a bit much, maybe very close to not work properly?)
They may still work at 7k ohm but at this level they may be close to play-up....
I hope this help, and if anyone have some more info....
